Description

TECHNICAL FIELD

[0001] The application relates to the technical field of detection, in particular to an in-situ rapid detector for organic pollutants in soil and water based on multi-parameter fusion. BACKGROUND

[0002] With the acceleration of industrialization and the change of agricultural production mode, the pollution problem of organic pollutants in the soil and water environment is increasingly prominent. Such pollutants cover polycyclic aromatic hydrocarbons, organochlorine pesticides, phenolic compounds, petroleum hydrocarbons and various types, which have the characteristics of strong concealment, long degradation period and high biological accumulation. Not only will they destroy the ecological structure of the soil, reduce the soil fertility, affect the growth safety and quality of crops, but also will spread to the water environment through underground water penetration and surface runoff, threatening the safety of drinking water, and then through the food chain, posing potential risks to human health. Therefore, efficient and accurate detection of organic pollutants in soil and water has become an important demand in the fields of environmental protection, agricultural safety and public health protection.

[0003] In general, the in-situ rapid detector for organic pollutants lacks a special impurity filtering structure integrated with the reagent head, and relies on manual pretreatment or omits the filtering step. Not only is it easy to introduce secondary pollution and increase the operation breakpoint, but also the data will be distorted due to impurity interference with the detection system, which cannot guarantee the detection accuracy. The reagent head taking and placing mechanism is not convenient, and relies on manual holding or simple buckle operation. When batch detection is performed, the operation time is prolonged due to personnel fatigue and complicated steps, and there is a risk of reagent leakage, which seriously restricts the detection efficiency. Therefore, we propose an in-situ rapid detector for organic pollutants in soil and water based on multi-parameter fusion. SUMMARY

DETAILED DESCRIPTION

[0028] The specific embodiments of the present application will be further described below in conjunction with the accompanying drawings, and it should be noted that the description of these embodiments is used to help understand the present application, but does not constitute a limitation on the present application.

[0029] In addition, the technical features involved in each of the embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment one

[0031] The present application is based on a multi-parameter fusion soil and water in-situ rapid detection instrument. In the areas such as farmland and river basin around industrial parks, due to problems such as industrial wastewater leakage, agricultural fertilizer abuse, and solid waste leachate penetration, organic pollutants such as polycyclic aromatic hydrocarbons, organochlorine pesticides, and phenolic compounds are easily accumulated in soil and water. These pollutants not only destroy soil aggregate structure, reduce soil fertility, cause crop growth to be hindered and quality to be reduced, but also pollute drinking water sources through surface runoff and groundwater infiltration and diffusion, and even cause potential harm to human liver and nervous system through food chain bioaccumulation. The traditional detection method needs to collect soil or water samples manually and then bring them back to the laboratory, and then goes through complex pretreatment, instrument analysis and other steps. In addition, due to secondary pollution in the sampling process and changes in sample composition during transportation and storage, the detection results may deviate from the actual pollution situation, which makes it difficult to meet the needs of pollution emergency investigation and dynamic monitoring.

[0032] Therefore, in order to effectively solve the above problems, the application proposes a multi-parameter fusion-based in-situ rapid detector for organic pollutants in soil and water, as shown in the accompanying drawings Figures 1-8 The inside of the rapid detector 1 is provided with a separation-type reagent head 2 for separating impurities in water, the inside of the separation-type reagent head 2 is provided with an impurity filter screen 21 for filtering impurities, the inside of the rapid detector 1 is provided with a belt-off rack 22 for taking the separation-type reagent head 2 away from the upper side of the transparent detection reagent bottle 11, the lower end of the separation-type reagent head 2 is provided with a translation limiting rack 23 and an up-down limiting rack 24 for connecting the separation-type reagent head 2 with the transparent detection reagent bottle 11, and the left and right sides of the separation-type reagent head 2 are both connected with side plates.

[0051] Step four, at the same time, the telescopic head 32 will contact the translational limiting shelf 23 and push the translational limiting shelf 23 to move downward, so as to extract it from the inside of the positioning ring 5, and loosen the fixing of the horizontal position of the transparent detection reagent bottle 11 and the split reagent head 2;

[0052] Step five, then use the electric telescopic rod 31 back to pull the band off the shelf 22, this band off the shelf 22 will be in contact with the rear end of the side plate, at the same time because the band off the shelf 22 can't turn counterclockwise, will drive the separation type reagent head 2 forward, so as to separate the transparent detection reagent bottle 11 and the separation type reagent head 2, thus, the whole work flow is completed.
